BACKGROUND 1. Technical Field

The present disclosure relates to a semiconductor device package, and to a semiconductor device package including a carrier with a patterned conductive layer and a lid with a patterned conductive layer, the patterned conductive layer of the carrier and the patterned conductive layer of the lid forming an electrical loop.

2. Description of the Related Art

In an optical device package, a light source is disposed on a carrier and a transparent lid is attached to the carrier to cover the light source. To prevent light of the light source from directly shining in someone's eyes should the transparent lid be detached from the carrier, an additional opaque lid may be used to secure the transparent lid to the carrier. However, including the opaque lid may increase a cost of the optical device package. Moreover, the opaque lid may adversely affect performance of the optical device package (e.g. an area of the transparent lid through which light passes may be decreased). Further, the opaque lid may increase a size/dimensions of the optical device package.

FIG. 1B is a perspective view of a semiconductor device package 1′ in accordance with some embodiments of the present disclosure.

A size (e.g. a length, a width, and/or a thickness) of the adhesive layer 14 may be flexibly set according to design specifications. The adhesive layer 14 may include two portions respectively disposed on the two opposite sides of the carrier 10, and the portions may be discontinuous. The portions may be separated or isolated.

The lid 12 is secured to the carrier 10 via the conductive element 13, the adhesive layer 14, and the adhesive layer 15. In some embodiments, the adhesive layer 15 may be omitted, or replaced by the adhesive layer 14.

FIG. 1C is a perspective view of a semiconductor device package 1″ in accordance with some embodiments of the present disclosure. The semiconductor device package 1″ of FIG. 1C is similar to the semiconductor device package 1′ of FIG. 1B, except that an adhesive layer 15′ partially surrounds the adhesive layer 14. The adhesive layer 15′ surrounds the semiconductor device 11. The adhesive layer 15′ may be adjacent to the adhesive layer 14. The adhesive layer 15′ may be spaced from the adhesive layer 14. The adhesive layer 15′ may contact the adhesive layer 14. The adhesive layer 15′ may extend along three sides of the carrier 10, which can provide for the lid 12 being attached to the carrier 10 securely.

FIG. 1D is a layout corresponding to the semiconductor device packages 1/1′/1″ according to some embodiments of the present disclosure. The patterned conductive layer 10 d may be a leadframe. The patterned conductive layer 10 d may be electrically connected to a system board (e.g. a printed circuit board (PCB)). The patterned conductive layer 10 d includes the conductive pads 101, 102, 103, and 104. Two conductive posts 10 b are respectively disposed on the pads 103 and 104. The pad 101 is electrically connected to the pad 102. The pads 103 and 104 are electrically isolated from the pads 101 and 102.

FIG. 1E is a cross-sectional view of the semiconductor device package 1″ across line 1E in FIG. 1C according to some embodiments of the present disclosure. The conductive element 13 and the adhesive layer 14 are disposed between the carrier 10 and the lid 12. The lid 12 is attached on the carrier 10 via the conductive element 13 and the adhesive layer 14. The patterned conductive layer 121 is electrically connected to the conductive element 13.

The carrier 10 has an upper surface 10 a 1 and a side surface 10 a 2. The side surface 10 a 2 has a slope. The accommodating space (S) is defined by the side surface 10 a 2. The accommodating space (S) may increase in area in a direction towards the lid 12. The conductive post 10 b has an upper surface 10 b 1. The upper surface 10 a 1 of the encapsulant 10 a and the upper surface 10 b 1 of the conductive post 10 b are substantially coplanar.

The conductive element 13 is disposed on the carrier 10. The conductive element 13 is disposed between the patterned conductive layer 121 and the conductive post 10 b. The conductive element 13 is surrounded by the adhesive layer 14. The patterned conductive layer 121 is surrounded by the adhesive layer 14. The patterned conductive layer 121 is covered by the adhesive layer 14. The patterned conductive layer 121 is electrically connected to the conductive posts 10 b. The pad 103 is electrically connected to the pad 104 via the patterned conductive layer 121 and the conductive posts 10 b. The pads 103 and 104 of the patterned conductive layer 10 d and the patterned conductive layer 121 constitute at least part of an electric circuit, and may constitute an open circuit. The pads 103 and 104 of the patterned conductive layer 10 d, the conductive layer 10 c, the conductive posts 10 b, and the patterned conductive layer 121 constitute at least part of an electric circuit, and may constitute an open circuit. The pads 103 and 104 are electrically connected to an external device. Once the lid 12 is detached from the carrier 10, a short circuit occurs (e.g. between the pad 103 and the pad 104). When the short circuit is detected by the external device, the power of the semiconductor device 11 may be cut off. Accordingly, if the semiconductor device 11 is a light emitting device, the semiconductor device 11 would stop operating, thus avoiding shining light directly in to a person's eyes (e.g. a person who removed the lid 12), or avoiding light pollution or emission of light that is otherwise undesirable.

The adhesive layer 15′ is disposed between the carrier 10 and the lid 12. The lid 12 is attached on the carrier 10 via the adhesive layer 15′.

The channel (C) defined by the carrier 10 and the lid 12 may be used as an air or liquid venting channel to fluidly release vapor or moisture. The channel (C) can help to prevent a pop-corn effect (e.g. expansion that may lead to undesired separation of components) during a thermal cycle in an operation of manufacturing the semiconductor device package.

The encapsulant 20 a may include a molding compound, a ceramic material, or other suitable materials. The encapsulant 20 a encapsulates the conductive post 20 b. The encapsulant 10 a and the encapsulant 20 a define the accommodating space (S). The conductive post 20 b extends between the conductive element 13 and the carrier 10. The conductive post 20 b aligns with the conductive post 10 b. The conductive post 20 b may be a solid cylindrical post, a solid square post, or a solid post with a suitable shape. The shape of the conductive post 20 b may be the same as the shape of the conductive post 10 b. The shape of the conductive post 20 b may be different from the shape of the conductive post 10 b. The through hole 20 c is disposed on one side wall of the carrier 20, such as on a side wall opposite to a side wall adjacent to which the conductive posts 10 b and 20 b are disposed. In some embodiments, one or more through holes 20 c may be disposed on one or more other side walls of the carrier 20. The through hole 20 c is in fluid/air communication with the accommodating space (S). The through hole 20 c may be used as an air venting hole to fluidly release vapor or moisture.

The material of the encapsulant 20 a of the carrier 20 may be different from the material of the encapsulant 10 a of the carrier 10. The encapsulant 20 a of the carrier 20 has an upper surface 20 a 1, a side surface 20 a 2, and a lower surface 20 a 3 opposite to the upper surface 20 a 1. The accommodating space (S) is defined by the side surface 10 a 2 of the carrier 10 and the side surface 20 a 2 of the carrier 20. The lower surface 20 a 3 of the carrier 20 may conform to the upper surface 10 a 1 of the carrier 10. The side surface 20 a 2 may have a slope. The side surface 20 a 2 may have a slope that is less than (e.g. is about 0.9 times or less, about 0.8 times or less, or about 0.7 times or less) a slope of the side surface 10 a 2.

The conductive post 20 b of the carrier 20 has an upper surface 20 b 1 and a lower surface 20 b 2. The upper surface 20 a 1 of the encapsulant 20 a and the upper surface 20 b 1 of the conductive post 20 b are substantially coplanar. The lower surface 20 b 2 of the conductive post 20 b contacts the upper surface 10 b 1 of the conductive post 10 b.
